NexaKey NX-K150B No-Touch Infrared Sensor Switch
The NexaKey NX-K150B No-Touch Infrared Sensor Switch is a precision-engineered, contactless exit solution built for modern access control systems where hygiene, space efficiency, and reliable performance are non-negotiable. Designed with a distinctive slim 150 × 40 × 14 mm vertical profile, the NX-K150B mounts cleanly on narrow door frames, glass partitions, and tight wall spaces where conventional square-panel exit buttons simply do not fit — making it a standout choice for architects, security integrators, and facility managers across Bangladesh.
At its core, the NX-K150B is a wave-to-open infrared sensor switch — users wave a hand within the 5–20 cm adjustable sensing range, and the door release triggers instantly. This eliminates every physical touchpoint on shared doors, reducing the risk of cross-contamination in hospitals, clinics, retail entrances, building lobbies, and corporate offices. The contactless mechanism is not just hygienic — it also removes mechanical wear entirely, extending the operational lifespan of the door control system.
Powering on DC 12–24V, the NX-K150B is compatible with a wide range of access control power supplies and supports NO/NC/COM relay output contacts, ensuring plug-and-play integration with magnetic locks, electric strikes, electromagnetic locks, and any standard access control panel currently in use. Its adjustable time delay from 0–30 seconds gives security administrators full control over how long the door remains unlocked after each trigger — a critical setting for server rooms, banking halls, hospital wards, and pharmaceutical storage areas where controlled access is mandatory.
A dual-color LED indicator — blue during standby, green upon activation — delivers instant visual confirmation at every use. For outdoor or semi-exposed installations, the optional NX-K150B-W weatherproof variant extends reliable operation to sheltered outdoor doorways, retail entrances, and covered parking entry points.
Certified to CE, FCC, and RoHS international standards and backed by a 12-month manufacturer warranty, the NX-K150B is a verified, compliance-safe investment for any professional access control deployment in Bangladesh.
